Application filed June 10, 1914. Serial No. 844,141.

To all whom it may concern:

Be it known that I, FRANK J. KAUFMAN, a citizen of the United States, and a resident of the city of Columbus, county of Franklin, and State of Ohio, have invented an Improvement in fork-Holders for the Sealing of Cartons, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a-work holder comprising a stand or form, to be used in connection with the sealing of fiber cartons Or the like, and consisting in the provision of suitable adjustable means for holding the box or carton during the sealing operation, the whole being so constructed that one stand with adjustable or interchangeable tops may be used in the sealing of several diiferent sized cartons, thus 0bviating the necessity, heretofore existing, of

to the cartons has however, been seriously hindered by the lack of suitable means for holding the carton during the sealing operation. This is especially true of that portion of the operation of sealing which is termed in the trade making up the cartons, 2" 6., preparing them for packing with the goods to be shipped therein. To facihtate this portion of the operation, thereby shortening the time and minimizing the labor heretofore required, the present device has been con structed. A further object of the present invention is to provide a stand or formof such improved construction that theeqrupment required for making up many different sizes of boxes is simplified and materially reduced.

It has been suggested heretofore that a form consisting of a stand and a top of such size that it will fit into the box to be sealed be provided, over which the box may be made up ready to receive whatever s to be packed therein. Where several different sizes of cartons were used, as many dlfferent stands were required. The present invention contemplates the use of one stand or support Fig. 2 is a front elevation of the stand member;

Fig. 3 is a plan of three interchangeable top pieces, the means of attaching the same to the stand being shown thereon;

Figs. 4L and 5 are detail views of means for;i securing an adjustable stop to the stand; an

Fig. 6 is a perspective of the stand as it would be used in relation to the bench upon which are mounted a gummed tape delivering machine and a supply of liquid adhesive, a carton being shown in outline upon the form.

Referring to Fig. l of the drawings, the stand is seen to comprise two upright members a and b, suitably braced and connected at the top. Means are provided on the top of the stand by which interchangeable top pieces, hereinafter referred to, may be secured thereto, the attaching means being herein shown as a cleat c. Verticalslots d and c are provided in the end pieces a and b of the stand and an adjustable stop or cross-bar f is provided to pass through these slots. This crossbar may be adjusted in any desired position with relation to the top of the stand in order to hold the carton on the stand in proper relation to the top thereof, as will appear from Fig. 5 of the drawings. Interchangeable heads or top members, 9, 7t, and z of any desired size, the size being determined by the size of the cartons to be sealed, are provided as shown in Fig. 3. Each interchangeable top piece is provided with means of attachment corresponding to the means of attachment on the stand, the means being shown herein as a cleat *j adapted to interlock with the cleat c on the top of the stand. It is contemplated that attaching means other than those shown herein may be employed, the object being to provide means whereby the tops may be quickly secured to and removed from the stand at the same time giving a firm connection between these parts.

In order to make the stop or cross-bar f adjustable in the slots (Z and c in the ends a and b of the stand, each slot is equipped on one side with a series of notches 7c and the cross bar at the point where it passes through these slots is provided with a series of teeth Z to engage the notches in. To insure firm engagement with the notches, a spring lever mechanism is provided on the crossbar at a point opposite the teeth. This mechanism is shown herein as a lever m pivoted at n and pressed against the smooth side of the slot by a coiled spring 0. Ohviously other means may be employed for making this cross-bar adjustable with relation to the top of the stand. In order to adjust the cross-bar the operator graspsthe bar and by pressing the lever m toward the bar releases the teeth Z from engagement with the notches 7c The bar may then be moved up or down in the slots 0 and d as desired and upon releasing the lever the teeth will again firmly engage the notches. When a carton is being made up over the form, this cross-bar, having been adjusted to the first carton of a number of the same size to be sealed, acts as a stop upon which rest the flaps of the open end of the carton; thus automatically positioning the carton for the operation of sealing, all as will appear from Fig. 6 of the drawings.

Fiber cartons are usually collapsed when delivered to the users and to prepare these cartons to be packed with goods for shipment they must be expanded and made up, as it is termed. The operation of: making up the cartons when the present invention is used in connection therewith consists in first selecting one of the interchangeable tops which will fit inside the carton. This top is placed on the stand and secured thereto by means of the interlocking cleats. The

stand is positioned adjacent a bench upon which is mounted a gummed tape machine and a supply of liquid adhesive. The expanded carton blank is slipped down over the form and the stop or cross-bar adjusted so that the flaps of the open end will rest thereon. Upon making up subsequent cartons of the same size this cross piece will automatically position the carton upon the form. The flaps of the box or carton which will constitute the bottom thereof, are then folded inwardly and liquid adhesive is applied between the inner and outer flaps which are thereupon pressed firmly together. Strips of tape of such length that they will extend across the box and overlap the edges to a certain predetermined extent are then drawn from the gummed tape machine and pasted crosswise of the box at the ends and in the center. Another strip of tape of suflicient length is drawn from the machine and applied over the center seam formed by the side flaps, this strip likewise extending down the sides of the box as desired. This operation of sealing will be readily understood by referring to Fig. 6 of the drawings, wherein a box p is shown in outline on the form and a sealing machine 9 is shown on a bench 1' adjacent to the sealing form. When the bottom of the box is thus made up the carton is removed from the form and is ready to be packed for shipment. The sealing of the top of the carton after packing may be accomplished in the usual manner.

It is apparent from the foregoing description that the present invention consisting, as it does, of adjustable means for holding cartons to be sealed or made up, will be of value in overcoming certain difiicnlties heretofore existing in this art by first, providing means for holding the carton and second, by making such means adjustable to accommodate cartons of varying sizes.

I claim as my invention:

1. The combination to form a complete sealing and work-holding device for fiber cartons, of a bench for supporting the sealing materials, a stand for holding substantially on a level therewith and adjacent thereto, the fiber cartons to be sealed, said stand having a flanged cleat and a set of interchangeable heads adapted to fit on the top of the stand for the purpose of supporting and presenting to the bench cartons of diiierent sizes for sealing, each of said heads being provided with a pair of flanged cleats adapted to engage the flanged cleat mounted on the stand, a blank positioning bar slidably mounted in said stand and underlying said flanged cleat, and a yielding bar locking member adapted to hold said bar in any desired operative position.
